An explosion-proof conductive slip ring conducts electricity through the relative friction between conductive contact materials, so in principle, electric sparks cannot be avoided. Conventional conductive slip rings usually focus on electrical performance, while protection is relatively weak. Therefore, the use of non-explosion-proof conductive slip rings will be a major potential safety hazard in explosive environments.
The explosion-proof slip ring starts from its principle, structure, and materials, and combines its own experience in developing and producing highly reliable conductive slip rings for many years to develop an explosion-proof conductive slip ring. At the same time, it meets the requirements of an explosive gas environment and explosive dust environment. The protection grade is IP68 explosion-proof slip ring. The product has passed the certification of the national authority - Shenzhen Institute of Explosion-proof Research and has obtained the explosion-proof certificate of explosion-proof conductive slip ring.
Class iB of explosion-proof slip ring limits the energy of ignition source and electrical equipment that cannot ignite explosive gas mixture under normal operation and one fault. Under normal operation, the safety factor is 2.0; In the case of one fault, the safety factor is 1.5. During normal operation, contacts with sparks must be protected by flameproof enclosures or gas-tight enclosures, and the safety factor in case of a fault is 1.0.
